Why My Mossberg 590 Side Saddle Is Necessary
I’ve found that having a Mossberg 590 Side Saddle on my shotgun is an absolute game-changer. First, it keeps extra shells right where I need them—on the side of the gun—so I can reload quickly without fumbling around for ammo. When seconds count, having those extra rounds within easy reach makes a huge difference in my confidence and readiness.
Another reason I rely on the side saddle is the improved balance it provides. Instead of carrying loose shells in a pouch or pocket, the side saddle distributes the weight evenly, making the shotgun feel more natural to handle. This helps me stay steady and precise, whether I’m at the range or in a real-world situation.
Lastly, it adds a level of customization to my Mossberg 590 that I really appreciate. It’s a simple upgrade but one that enhances both functionality and the overall feel of my shotgun. For me, the side saddle isn’t just an accessory—it’s a necessity that boosts my performance and peace of mind.
My Buying Guides on Mossberg 590 Side Saddle
When I decided to upgrade my Mossberg 590, adding a side saddle was one of the best moves I made. It significantly improved my reload speed and overall handling. If you’re thinking about getting one, here’s what I learned through my buying journey.
Why Choose a Mossberg 590 Side Saddle?
For me, the side saddle offers quick access to extra shells without fumbling through a pouch or bag. It mounts directly on the receiver, keeping everything within reach. This is especially handy in high-pressure situations or when you want to keep your gear compact and streamlined.
Material and Build Quality
I looked for side saddles made from durable materials like aluminum or high-grade polymer. Aluminum models tend to be sturdier and last longer, but polymer options can be lighter and more budget-friendly. Whichever you choose, make sure it’s corrosion-resistant since your shotgun might see harsh conditions.
Capacity and Shell Compatibility
Most Mossberg 590 side saddles hold 5 to 6 shells, which is a good balance between extra ammo and weight. Confirm that the side saddle matches the shell size you use—typically 12 gauge 2.75” or 3” shells. I made sure mine was compatible with the shells I run to avoid any feeding issues.
Ease of Installation
One thing I appreciated was how straightforward some side saddles were to install. Many models use the existing screw holes on the receiver, so no permanent modifications are needed. I recommend checking if the side saddle comes with all necessary hardware and clear instructions.
Fit and Finish
A snug fit is crucial to prevent rattling or shifting during use. When I bought mine, I paid attention to the mounting design and reviews mentioning fitment. Also, consider the finish—some side saddles come in matte black, while others offer anodized or coated finishes that match your shotgun’s look.
Price vs. Performance
Side saddles can range from budget options under $30 to premium models over $100. I balanced my choice by reading user reviews and considering how often I would rely on the side saddle. For casual use, a mid-range model offered great value and reliability.
Additional Features to Consider
Some side saddles come with extra features like built-in shell carriers for different shell lengths or ambidextrous designs for left-handed shooters. I also noticed models with rubberized retention tabs that hold shells more securely. Think about what features matter most for your specific needs.
Final Thoughts
Buying a Mossberg 590 side saddle definitely enhanced my shotgun setup. By focusing on compatibility, durability, and ease of installation, I found a side saddle that fits my style and shooting requirements. If you invest some time in research like I did, you’ll find a side saddle that makes your Mossberg 590 even more versatile and ready for action.
